Potential Sources for New Lifters

[Jagdpanzer]

Researching potential sources for new lifters to the original GM PN 17120991 lifters from AC Rochester our engines were originally built with.

Discovered the same style bucket lifter is also used in the GM Quad 4 engine as well as some foreign engines built by Audi VW and others.

Here are the aftermarket alternatives I've identified so far:


Current AC Delco HL110C

Milling JB-6051

Federal Mogul Sealed Power HT2236

Clevite 213-1747

Prices range from less than $10 to over $30 each.

Anyone care to share their experiences with any of these?

Particularly interested how they compare with the original GM lifters in terms of performance and durability.

Thanks,

Phil

Phil,
another option is the lightweight VW/Audi lifters made by INA. Stock GM/AC Delco pieces are heavy...about 75 grams each. The INA ones are less than 50 grams. We have a set to test with my new cams on the spintron to ensure they are reliable to at least 8000 with my valvetrain pieces. (No, Kevin, I'm not really going to spin my motor that high....:mrgreen:)

The installed height would have to be checked thoroughly if using stock valves and valve stem height. In my case, it stacks out perfectly with my new valves, but your mileage may vary.

They're about $12 each.

Thanks Todd,
Great tip!
Keep us posted on how they test out.

That's OK mine is chiped to 8,200 :sign10:

had a little set back, did not hold water pressure. GO BIG or reWELD:wink:

Uh oh. Does that mean the rest of us will have to wait even longer to get our parts done? No cutting in the line, Kevin :razz:

Don't worry about it Kevin, just puncture the others and call it water injection. :mrgreen:

Why would you need to check the installed height? Specs somehow different? Are your valves not stock height? I'm guessing that you looked into hardness compatability?
Be awesome if the VW/Audi lifters work, $12 and 25g lighter - whats not to like.

already fixed and in the mail back home:mrgreen:

Why would you need to check the installed height? Specs somehow different?
There is less than 1 mm difference in uncompressed foot to face distance. Which is still a lot, really, considering the lifter travel is .120". Hard to tell exactly how that difference would change with oil pressure, but I suspect not much. Works fine for me, perfect in fact, because I have +1mm valve tips.

Are your valves not stock height?
Nope, a mm longer tip. Originally designed it that way to leave room for a shim under solid buckets, and get taller spring installed height. The solid bucket idea faded away, but it fortuitously turns out that the VW lifters are a perfect fit with my combination. The valve seat cut might have had a small interaction here with the stackup height, but relatively small I think.

I'm guessing that you looked into hardness compatability?
Yep. No worries there.

Phil,

Thanks for asking this question as I am looking for some new lifters right now. I am thinking of going with the HT-2236 Sealed Power and hope someone can chime in about their experience with these or what they have heard. I have to search my old, old list server emails as I remember something mentioned about 5 years ago or so.

We sell brand new GM lifters for $16.99 each, or $499.99 per set of 32, that's a fantastic price for 32 OEM lifters.

Thanks Kurt, I'll consider it in my quest for lifters. Your site listed them at $34.20 each so I started looking for other options.

I thought you sold the HT-2236 Sealer Power at one time too?

I guess I am a little confused by the lifter deal.

While I understand the benefits of lighter and/or shim under bucket, why is there such a issue with stock replacement? Having rebuilt many dohc motors, the only time these were replaced were if there was a wear issue, and different sized shims were required to meet factory specs.

Do people do a full replacement with a rebuild on these things as a precautionary? :icon_scra

I my case I purchased a set heads that did not come with lifters.
I'm sure for most applications the standard GM supplied lifters will do just fine.

[HAWAIIZR-1]

In my case I am rebuilding my motor that had 53K miles and not sure I want to put the old lifters back in even though it would probably be okay. I am going to do Stage I regrinds so I thought I should put in new lifters. I'm still not sure since there are LT5 with over 100K miles and no issues with lifters or at least I have not heard a lot of issues with lifter failures, but will do more research. I really hate to put it all back together and in a year or somerwhere down the road have to replace some failed lifters; this is not a standard SBC and a big deal to me. My other concern was replacing with aftermarket as Sealed Power appears to be made in China and not sure about the quality, but where are GM lifters made? Sealed Power is a very reputable company so I would imagine some strict standards are being held with their name on the line.

Rob, no need to change lifters hey i know someone who had stock 60k mile lifters went with regrind cams back to stock cams back to a different set of regrinds with same used lifters now he has Sealed Power no issues.

Pete

[todesengel]

Thanks. I just couldn't wrap my mind around why someone would change them if they were within spec.
